To all whom it may concern:

Be itknown that I, FRANK S'rnnioma citizen of the United States, anda resident of Jolietfcounty of Will, and State of Illinois, have invented certain new and useful Improvements in Dough-Molding Machines, of which the following is declared to be a full, clear, and exact description.

This invention relates to dough molding machines, and its primary object is to improve upon the construction and operation of machines of this class. The invention has particular reference to that type of dough molding machines, that employ rotating cylindrical bodies for curling or coiling a sheet of dough, and thereafter rolling and compressing it into loaf form. Heretofore much difiiculty has been encountered in the curling mechanism, and many unsuccessful attempts have been made to remedy this difficulty. I have overcome the obstacles in the present invention as embodied in the ma chine shown and described herein. The invention, therefore, consists, in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1, is a side elevation, partly broken away, of a dough molding machine, embodying a simple form of the present invention; Fig. 2, is a plan thereof; Fig. 3, is a vertical, longitudinal section taken on-the line 33 of Fig. 2, and Fig. 4 is an end view of the machine, looking in the direction of the arrow 4, in Fig. 1.

Referring to said drawings, the reference numeral 10, designates a supporting frame of strong and substantial construction, said frame comprising, in general, in two side frame members 11, 11, cross members 12 and legs 13. Secured to the side frame members 11, near one end of the machine are posts or standards 14, in which is mounted a rod .15, which carries one end of a rocking feed roll carrying frame 16, which as shown, comprises two side members 17, and a cross member 18. The side members 17, are carried by the rod 15, and the cross member 18, is supported upon the cross member 12, of the main frame, by two adjustment screws 19, which are threaded in ears 20, that project out from the cross member 18';" 'the screws rest on lugs 21, formed on the cross member 12, of the main frame.

Journaledupon the side members of the rocking frame 16, are two feed rollers 22, 23, which are arranged side by side, and mounted upon shafts 24, 25, that are journaled in bearing boxes on the side members 17, one pair of boxes being adjustably mounted on the side members,and adjustment screws 26, threaded in thecross member 18,,being employedfor effecting the adjustment of the roller 22. Sprocket wheels 27, secured upon the adjustment screws 26, and a sprocket chain 28, trained around said sprocket wheels, are provided for effecting simultaneous rotation of both adjustment screws, whenever one. is turned, to thereby change the location of the roll 22.

Above the feed rolls 22, 23, is a hopper 29, which is mounted on the rocking frame 16, and has transversely adjustable side boards 30, adjustably mounted on inclined boards 31. In the operation of the machine, the lumps of dough are dropped into the hopper 29, and onto the feed rolls 22, 23, between which they are compressed and fed to the sheeting roll as will appear later.

Below the feed rolls 22, 23, is a sheeting roll 32, which is of a largerdiameter than either feed roll, but driven at or approximately at the. same peripheral speed, and said sheeting roll 32, is mounted on a shaft 33, journaled in bearing boxes mounted on the side frame members 11. At the side of the sheeting roll 32, is a pulley 34, around whlch pulley is an apron or belt 35, of can vas or the like, which runs to and is trained around a pulley 36, mounted on a shaft 37, which is journaled in bearing boxes adjustably mounted on the side frame memhere 11, at one end of the machine. The upper portion of the apron runs on a table or platform 38, which is supported by the side members of the frame 10, and above said belt is a vertically adjustable pressure plate 39, which is supported from two bell crank levers 40, 41, by posts 42, that are secured to the pressure plate and have upper ends into of the .bell crank crank lever 40, is

horizontal slots in their which project pins 43, levers 40, 41. The bell The horizontal arms of the bell crank levers connect with the pressure plate or board as described, and the vertical arms of said levers are connected together by a link 46, to maintain parallelism between the pressure plate and apron at all points of adjustment of the pressure plate. A handle 47, onthe upper end of the vertical armof the bell crank lever 41, furnishes means whereby the pressure board may be raised or lowered by hand. A post 50, secured to the rod 44, is provided with a segmental slot 48, throughwhich projects a screw threaded pin 49, carried by the bell crank lever 41, and a screw threaded clamp nut 51, is threaded on said pin 49, and adapted, when screwed up against the post, to lock the bell crank lever and pressure board in any position of adjustment.

(Extending along each side edge of the pressure board or plate 39, is a side board or plate 52, which is carried by the rods 15, 44, that extend through boxes formed upon the upper edges of the side plates; set screws 53, threaded in said boxes and adapted to bear upon said rods furnish means for adj ustably clainping the side plates in place. The apron or belt 35, pressure plate 39, and side plates 52, provide a channel H or conduit whose cross sectional area may be increased I or decreased fordifferent sized loaves.

The sheeting'roll 32, and belted pulley 34,- form a crotch or pocket into which the sheets of dough are carried by the sheeting roll 32, the sheet of dough is thereby carried against the face ing up of the sheets of dough, I have provided a kneader-'54, above the crotch or pocket between the sheeting roll 32, and pulley 34, which kneader is in the form of a curved plate, carried by a rock shaft 55,' until it emerges 1n the form nected by a link 57, to an eccentric pin 58, on a roll driving sprocket wheel 59, the arrangement being such that the plate is rocked back and forth once during each revolution of the sprocket wheel 59. The effect is that, from the time the belted curl up the dough,.it is kneaded down against the belted pulley 34, and temporarily held back from rising and following said pulley in the form of a sheet, but is effectively curled or coiled up before it is carried under the upturned end of the taken up and thefeed of the apron or belt modifications of th by, the belt untilit emerges at the discharge end, in the form of a loaf.

Any suitable gearing may be employed for driving the rolls and pulleys, and. in the simple form illustrated, a gear wheel 60, is shown fast upon the shaft 33, which gear wheel maybe driven from a motor or from any other suitable source of power asdesired. The roll shafts 24, 25, 33 and pulley have sprocket wheels 62, 59, 64, secured thereon, and a sprocket chain 6, is trained around them as shown in Fig. 1, whereby the several rolls and pulley are driven in the directions of the arrows. A tension idler 67, carried by a lever 68, is pressed against the chain 66, by aspring 69, secured to one of the legs 13, of the main .frame. The slack in the chain is thereby roll carrying frame permitted to use without unnecessarily tightening the chain upon the sprocket wheels. .The gearing is timed to drive the feed rolls, sheeting roll and belt pulley at spee Scrapers 7O 71 are secured to rods 72, 3, supported by the roll carrying frame 16, an engage the feed rolls as shown to scrape ofi any flour or dough that may accumulate thereon. flour hopper 74, is mounted back of the sheeting roll, and supplies said roll with flour.

n the operation of the machine lump dough are-dropped into the hopper 29, one at a time, and fall between the feed rolls 22, 23, which compress and force the lumps of dough down upon the sheeting roll 32, which in turn carries it under the feed roll 23, where it is flattened out in the form of a sheet of dough, and carried toward 'and against the apron around the which revolves in loaf at the discharge end.

In case the dough is hard, or in case a hard lump of dough passes between the feed roll 23, and the sheeting roll 32, the roll carrying frame is thereby raised slightly, thereare possible without departing from the spirit of this Lemma invention; myself to the exact form of the invention shown and described, but intend in the following claims to point out all of the invention disclosed herein.
